Description
図1は、本発明の実施の形態に係る半導体装置の平面図である。半導体装置10はパワーMOSFETで形成されている。半導体装置10は、耐圧維持領域12を備えている。耐圧維持領域12は半導体装置10の耐圧を高めるために形成された環状の構造である。耐圧維持領域12に囲まれた場所にはゲート配線14が形成されている。ゲート配線14はアルミで形成されている。ゲート配線14と接してゲートパッド16が接続されている。ゲートパッド16は、ゲート配線14と同一材料で形成されているが、ワイヤボンディングのためにゲート配線14よりは幅が広く形成されている。耐圧維持領域12に囲まれた場所にはさらにエミッタパッド18が形成されている。さらに、ゲート配線14、ゲートパッド16、及びエミッタパッド18の絶縁確保のために絶縁膜20が形成されている。
